Forbes reports that the secondary market is seeing robust sales for the tour, with an average price of $255.82 across all 13 North American dates. The most expensive market thus far is Edmonton, which has driven the average ticket up to $573.37, with Vancouver slightly behind at $561.23. The cheapest stop, meanwhile, is the group's Aug. 22 stop at Gillette Stadium outside of Boston, which is going for $205.87. Another relative bargain: the band's Sept. 25 date at AT&T Park in San Francisco, which has an average price of $218.71.

Of course, an inflated secondary market for tours from veteran rock acts is nothing new, and with the members of AC/DC getting on in years — guitarist Angus Young is the baby of the bunch at 59 — you never know which show might be your last chance to see them perform in person, so for fans who can afford them, these tickets are probably worth it even at a higher price. For the rest of us, there's always YouTube.
